The essential concept of this invention involves a series ofwalLsupported sections each with a panel-concealed heating corewherewith is associated either a damper or an air-splitter, adjacentsections being secured together by inside and outside corner trimassemblies and joint cover trims, the ends of the sections being closedby end trim assemblies.

An improved base-board convector embodying the foregoing conceptcomprises a series of heating sections A, inside and outside cornertrims B and C, end trims D, and joint cover trims E.

A section A of this improved base-board convector comprises a wallmounting 15 whereto are secured brackets 16 from which a heating core 17is suspended by hangers 18 and concealed behind front panels 19 andabove which core is arranged either a damper 21 or an air-splitter 22.

The wall-mounting 15 is a sheet metal stamping formed with a right angledisposed back 23 and top 24. The top 24 has its front edge taperedslightly downward and turned inwardly to form a head 26 terminating inan upwardly-disposed narrow perimetrical flange 27 (Fig. 3), withinwhich flanged bead 26 are retained damper hinge clips 25. The back 23 ofeach mounting 15 is of a height such that with its lower edge 28 restingon the floor the back 23 lies flat against the wall and disposes thetransverse top 24 at the desired elevation above the floor and sorelatively positions the parts assembled thereon as to make heating mosteffective. Suitable apertures (not here shown) are drilled in the back23 by the installers to permit it to be anchored to the wall.

The brackets 16, of which there may be two or more to a length of eachmounting 15, are metal stampings from the bases 29 of which extend theright-angularlydisposed, vertically-spaced flanges 31 and 32. Mediallythe flange 31 is formed with a U-shaped recess 33 and has its upperouter corner extended to form an upwardlydisposed rounded prong 34. Nearits lower rear portion is an aperture 36 for the reception of one end ofthe hanger 18. The recess 33 is provided to accommodate a return pipefor the heating core 17 when, for some reason, it is desired to have theinlet and outlet supply pipes at one end of the stretch of convection.

The flange 32 has its upper edge 37 at right angles to the base 29 butits lower edge 38 is inclined upwardly and notched near the outer end toprovide a downwardly-disposed rounded prong 39. These flanges 31 and 32are so spaced from each other vertically that the prongs 34 and 39 mayhave the panel 19 releasably snapped thereon, as so clearly shown inFigs. 3 and 5.

The brackets 16 are so positioned on the mounting back 23 that with thepanel 19 in place on the prongs 34 and 39 there is a space 35 above thefloor and a space 40 below the mounting top 24 to provide for therequisite circulation of air into, and up through, and from the spacewherein the core 17 is suspended.

The heating core 17 is of a conventional character comprising a tube 41on which are bonded rectangularlyshaped axially-spaced fins 42.

The hanger 18 (Figs. 2 and 3), which is one of the special features ofthis improved base-board convector, is a piece of wire bent to simulatethe general form of an L with an outwardly-disposed loop 43 formed nearthe junction of the two leg parts of the L. The lowerhorizontally-disposed leg part is curved downwardly to provide a cradle44 for the pipe 41 on the heating core 17.

The free ends of the wire hanger 18 are bent to form hooks 46 and 47.The loop 43 and the hook 47 are so shaped and spaced that the oppositeextreme peripheral points are spaced apart a distance but slightly lessthan the front-to-rear distance between the front face of the bracketbase 29 and the inside face of the front panel 19, when the latter is inplace on the prongs 34 and 39, as shown in Fig. 3. Thus, when the hook46 is inserted in the aperture 36 in the flange 31 and the heating core17 is suspended on two or more of these hangers 18 the edges of the fins42 are held free of contact with the bracket bases 29 and the panel 19.Accordingly, when there is an expansion and contraction of the heatingcore 17 there is no tinkling sound created by the dragging of the edgesof the fins 42 on these parts, a sound which can be very annoying tooccupants of a room when such expansion and contraction arealternatively taking place, and no provision has been made forpreventing contact of the fins edges with these housing parts.

The panel 19, for each section A of this base-board convector, is simplya sheet of metal. The opposite longitudinal peripheral portions are bentto provide annual beads 48 and 48' which are so formed that with just alittle pressure they may be sprung over the curved extremities of theprongs 34 and 39, to insure the panels being held firmly in place onthese brackets 16 to conceal the heating core 17.

As previously noted, a damper 21 or an air-splitter 22 may be arrangedabove the heating core to influence the heated air flow through theoutlet 40.

The damper 21, suitable for use with a section A has one longitudinaledge rolled to form an annular bead 49 whereby the damper 21 isswingably held on the mountposed with its angle facing out and hasbrackets 59 bonded at the upper outer corners of the two sides of thesupport 56. Each of these brackets 59 is formed with a base 60, a gusset61 and a plate 62. The plate 62 of each such bracket 59 is offsetmedially to form a ledge 63. The free outer edge of the ledge 63 isflush with the adjacent verticle edge of the upright 56 to which thebracket is bonded. The inner short edge of the offset 63 is spaced fromthe support 56 to form a slot 65 (Fig. 10) equal to the thickness of theback 23 of the mounting 15. Intermediate these two brackets 59 thesupport 56 is formed with inwardly-extending flanges 64 disposed in theplane of the bracket plates 62.

The top member 57 is a flat rectangular-shaped piece of metal with anarcuate-shaped depending lip 66 formed at the forward corner thereof.This top member is practically square and of a width substantially equalto the width of the mounting top 24. The top member 57 is bonded,preferably by spot welding, to the bracket plates 62 and the supportflanges 64 with the rear right angle edges flush with the rear faces ofthe upright support 56 and the lip 66 disposed forwardly of the support56. Between the ledge 63 and the under face of the top 57 is constituteda slot 65a (Figs. 8 and 9).

The front plate 58 is of quarter circular cross section with an offsetupwardly-extending lip 67, formed at the upper end, and aninwardly-curved bead 68, formed at the lower end. Rearwardly-curvingwings 69 are also ing-top bead 26 by two or more spring hinge clips 25(Figs. 3 and 14). These spring clips 25 are somewhat V-shape, one leg ofwhich has its free end bent to constitute a socket 51 to yieldinglyembrace the damper bead 49. These clips 25 are sprung into the bead 26to seat rearwardly of the flange 27 and against which the damper bead 49is firmly held by the free end sockets 51 of two or more of the clips25.

The air-splitter 22 is a curved strip of sheet metal formed with areinforcing rib 52 along the upper longitudinal edge and a V-disposedflange 52a (Fig. 5) along the other edge. An air-splitter 22 issupported on two or more bracket flanges 31 by special clips 53 (Figs. 5and 15). Each such clip has prongs 54 punched out from the face thereofat the opposite lower corners. The opposite edge is tapered to an apexat which point a slot 55 extends inwardly toward the middle. In widththis slot 55 is slightly greater than the thickness of the material fromwhich the air-splitter 22 is made so that with the V-flanged edge 52apressed into the slot 55 the airsplitter 22 is frictionally held inplace. With one of these clips 53 astride the upper edges of eachbracket flange 31 the air-splitter 22 is positioned nearly medially inthe heated air outlet 40.

The corner trims B and C are constructed to provide an ornamentalcontinuity for adjacent and angularly-disposed sections A. Although thethree pieces of which each such two differently-placed trims B and C areformed are differently shaped they are fundamentally of the same generalconstruction and purpose, as is most evident from 56, 57 and 58 but forthe outside corner trim are identified by the reference numerals 56, 57'and 58'.

The support 56, for the inside corner trim B, is disformed adjacent theupper edges of the plate 58. The lower ends of these wings 69 arecurvedly recessed at 69:: in opposed relationship to the ends of thecorresponding curved bead 68 and spaced from such bead 68 a distanceequal to the vertical outside dimension of the front panel 19. Thefunction of these recessed wings 69 coacting with the bead 68 willappear presently.

The support 56' and front panel 58' for the outside corner trim C, intheir overall horizontal dimensions, are more like the horizontaldimensions of the front panel 58 and support 56 respectively of theinside trim C just described but similar to the support 56 and frontpanel 58 respectively in their transverse cross-sectional form. Thesupport 56' is disposed with its right angle rearward. Brackets 59' arebonded at the upper ends of the two sides in abutting relationship.These brackets 59' are identical with the brackets 59, each having abase 60, a gusset 61' and a plate 62'. The plate 62' is medially 0&- setto form a ledge 63' the inner end of which is spaced from the side toform a slot 65a equal in thickness to the material out of which the back23 of the mounting 15 is made.

The top member 57' for this trim C is a flat rectangular piece of metalwith the rear corner cut out at 70 to fit around the upper end of thesupport 56. It is of a Width equal to that of the mounting top 24. Theforward perimetrical portions of the top member 57 are formed with acontinuous downwardly-disposed lip 66'. The top member 57 is bonded,preferably by spot welding, to the brackets 59 with the edges of theangular cut out 70 seated against the upper inside faces of the angleupright 56' and the lip 66 disposed outwardly of the brackets 59'.Between the ledge 63 and the under face of the top 57' is constituted aslot 6519 (Fig. 12).

The front plate 58 for the trim C is a right-angle shaped piece formedwith an inwardly-upwardly offset lip 67' along its upper edge and withinwardly-upwardly curved beads68 at lower opposite corners. It also hasinwardly-curved wings 69' formed adjacent the upper corners. The lowerends of these wings 69' are curvedly recessed at 69b in opposedrelationship to the corresponding end beads 68 and spaced from suchbeads a distance equal to the vertical outside dimension of the frontpanel 19. The function of these wings will appear presently.

The end cap trim D is quite similar in its general construction to theinner and outer corner trims B and C sesame in that the former eachcomprises an upright support 71, a top member 72 and a front plate 73.

The upright support 71, for an end trirn D, is of angle form with theangle facing out, and one section shorter than the other, as shown at 74in Figs. 6 and 7. At the top outer corner of the longer section is abracket 75 of identical form with the brackets 59 and 59. The bracket 75is formed with a base 76, a gusset 77 and a plate 78. The plate 78 ismedially offset to form a ledge 79 with the outer edge of the ledgeflush with the adjacent vertical edge of the upright support 71 and theinner end of the offset spaced from the support 71 to constitute a slot80 equal in thickness to the material out of which the back 23 of themounting 15 is made. The top edges of the member 71, at the angle, areformed with flanges 81 flush with the plate 78.

Along the opposite vertical edge of the support 71 is a strip 82 theends of which are bent to form beads 83 and 83. In longitudinalcross-sectional length the strip 82 is equal to the vertical outsidedimension of the front panel 19. This strip 82 is bonded to the face ofthe shorter section of the support 71, directly above the cutout (74),so that when the trim D is positioned on a heating section A the strip82 is disposed in horizontal alinement with the front panel 19 on theabove-mentioned bracket-flange prongs 34 and 39.

The top member 72, like the top members of the otherpreviously-described trims, is of rectangular form and in widthsubstantially equal to the width of the mounting top 24. The top member72 has the front thereof bent downward slightly out of the plane of themain part and is curved downwardly along that forward edge to provide alip 84. The top member 72 is bonded, preferably by spot-welding, to thebracket 75 and the flanges 81 with the rear right angle edges flush withthe rear faces of the upright support 71 and the front edge of the lip84 and the adjacent right angle edge respectively flush with the freevertical edges of the support 71 (see Figs. 6 and 7). Between the ledge79 and the under face of the plate is constituted a slot 80a (Fig. 7).

The front plate 73, for a trim D, is a flat piece of sheet metal with aninwardly-upwardly offset arcuate lip 85 and an inwardly-upwardly curvedbead 86 formed along the lower edge. Wings 87 are formed adjacent theupper corners. The lower ends of these wings 87 are curvedly recessed at87a in opposed relationship to the ends of the bead 86 and spaced fromsuch bead 86 a distance equal to the vertical outside dimension of thefront panel 19. The function of these recessed wings 87 will appearpresently.

The joint cover trim E (Fig. 13) comprises a unitary back-top member 89and a front plate 90. The backtop member 89 in cross section is almostthe same shape and dimension as the cross section form and height of themounting 15. The top 91 has the forward part inclined downwardly andterminating in a bead 92. This bead 92, however, does not terminate in aflange (27) as does the bead (26) on the mounting top (24).

The front plate 98 is a narrow strip in cross section identical with thefront panel 19. However, the distance between the beads 93 and 93 isequal to the vertical outside dimension of the front panel 19.

A stretch of base-board convection, constructed in accordance with thisinvention and such as shown in Fig. 1, is shipped to and installed onthe job in the following manner:

Each mounting 15 has the brackets 16 bondedin requisite position on theback 23. The several trims B, C and D have the supports, brackets, andtop members bonded together. The heating core 17 has the fins 42 bondedon the tubing 41. These three sub-assemblies and all the otherparts-front panel 19, the hangers 17, the front plates for the severaltrims, the dampers and/ or air-splitters, and the clips 25 and 53 arepacked knock-down and shipped to the job.

At the point of installation, the mountings 15 are set in position, withthe edges resting on the floor. The partially assembled corner trims Band C, and later the end trims D, are set on the contiguous, or exposed,ends of the respective sections A. This is effected by pushing theangular ends of the mountings 17'i. e, the corner junction of the back23 and top 24into the respective slots (65, 65, and 80, and 65a, 65b,and a) in the trims B, C, and D,

Holes are then drilled in the backs 23 of the several mountings, and inthe respective upright supports of the trims, at points where nails orscrews will penetrate into the studding to secure the complete assemblyin place.

When these parts are all secured in place, sections of the heating core17 are cradled in two or more hangers 18 and setin between the bracketflanges" 31 and 32 with the hanger hooks 46 inserted through theapertures in the flanges 31. Properly positioned these hangers 18suspend the core 17 so that the opposite vertical edges of the fins 42are disposed free of any contact with the front face of the bracketbases 29 and the inside face of the front panel 19, when the latter issnapped in position on the bracket prongs 34 and 39, as is clearlyindicated in Figs. 3 and '5.

If dampers 21 are to be used, the requisite clips 25 are seated in themounting-top beads 26 rearwardly of the flange 27. The bead 49 on adamper 21 then is seated in the clip socket 51 to bear against theflange 27. So positioned the damper 21 may be swung and frictionallyretained in desired positions to regulate the flow of heated air throughthe outlet 48.

If an air-splitter 22 is to be used, the requisite clips 53 arestraddled over the upper edges of bracket flanges 31 and the V-flangededge of the air-splitter pressed down into the slots 55, whereupon theair-splitter 22 is positioned to divide the heated air flow out throughthe outlet 48.

With the heating cores 17 and dampers 21 and/or airsplitters 22 inplace, the front panels 19 are next snapped onto the bracket prongs 34and 39 (Figs. 3 and 5). Following this the front plates (58, 58' and73), for the respective trims, are snapped into position. With each ofthese-except the joint cover trim Ethe front plate has the upper edgelip (67, 67 and set under the depending top member lip (66, 66' and 84)with the plate disposed at an outwardly-downwardly inclined angle. The

plate is then swung downwardly and inwardly to bring the recessed wings(69a, 69b, and 87a respectively) to slip over the top edges of the frontpanels 19 and allow the bottom beads (68, 68' and 86) to be snapped overthe under edges of the front panels 19.

With the end trims D the recessed wing 87 and the bead 86 at one sideseats over the opposite ends of the strip 82 (see Figs. 6 and 7).

Where a joint trim E is required, the top back member 89 is set in placeas is done with the upright supports for the other trims and later thefront 90 is snapped over the opposite ends of the front panels 19 ofadjacent sections A (Fig. 1).
